The invention discloses a lead wire structure and method for preventing ACF glue from overflowing to a display area. The lead wire structure comprises a display panel and a circuit board; lead wires are arranged between the display panel and the circuit board and include a plurality of longitudinal lead wires and horizontal lead wires, wherein each longitudinal lead wire is arranged after more than five horizontal lead wires are arranged. According to the lead wire structure and method for preventing ACF glue from overflowing to the display area, the method is simple and the operation is convenient; in hot-press gluing of a liquid crystal panel and an FPC (Flexible Printed Circuit), the problem that ACF glue overflows to the display area is solved effectively through the technological method of increasing the accommodating space of ACF glue and stopping ACF glue from overflowing to the display area, thereby ensuring the imaging quality of an LCD panel and saving the loss caused by the reason that displaying and imaging are influenced by overflowing glue in the production process for enterprises.
Description
technical field [0001] The invention relates to the field of liquid crystal panel manufacture, in particular to a method for attaching ACF (Anisotropic Conductive Film, one-way conductive adhesive) glue. Background technique [0002] With the development of electronic technology, people's daily life and work are increasingly inseparable from electronic products. As an important part of electronic products, LCD screens also closely affect people's experience. Therefore, the manufacture of LCD screens should be continuously improved. Methods and preparation techniques are particularly important. [0003] In the manufacturing process of the liquid crystal panel, when the liquid crystal display is connected to the FPC (Flexible Printed Circuit, flexible circuit board), the connection leads on the liquid crystal display and the connection leads on the FPC are precisely positioned by marks, and then hot-pressed. However, in order to ensure the electrical signal continuity between...
